A new study from IT solutions provider US Signal reveals that businesses are seeing a greater number of security challenges.  

The survey of security experts from a cross-section of organizations also shows 40 percent of respondents experienced at least one security incident in the last year, and 13 percent didn't know if they had.

The top three challenges are seen as: protecting against email-related threats like ransomware, malware and phishing; transitioning legacy systems that no longer receive security updates; and ensuring the company is always up to date with patches and current software versions.
